Section Eight
Legs- Two congruent sides on an isosceles triangle.
Vertex angle- The angle formed by the legs.
Base- The side opposite the vertex angle.
Base angles- The two angles the base as a side.
Isosceles Triangle Theorem- If two sides of a triangle are congruent, then the angles opposite the sides are congruent.
Converse Of Isosceles Triangle Theorem- If two angles of a triangle are congruent, then the sides opposite those angles are congruent.
Equilateral Triangle Corollary- If triangle is equilateral, then it is equiangular.
Equiangular Triangle Corollary- If a triangle is equiangular, then it is equilateral.
Vertex angle- The angle formed by the legs.
